Officials are warning folks to never fly drones over wildfire areas.

Two drones recently got too close to the Ross Fork Fire in Idaho’s Sawtooth mountains.

CBS 2 News reports one drone nearly crashed into one of the firefighting helicopters, forcing it to land.

Crews say the downtime could mean life or death — especially since the helicopters are needed if a firefighter gets hurt.

Flying a drone or other aircraft that interferes with firefighting efforts on public lands is a federal crime — punishable by up to a year in prison.
